Berlin is a city haunted by the past, built on layers of memory. Holger Raschke, founder of Berlins Taiga, a tour company that focuses on the Soviet history of the city and its surrounding areas, is also fascinated by the past. He grew up in Potsdam, at a time when the Soviet army was omnipresent, surrounded by barracks, fenced-off military facilities and gigantic military training grounds.

It lingers just beneath the grass of the Soviet War Memorial of Tiergarten, where 2,500 Soviet soldiers are buried beneath the unmarked, inconspicuous earth. It lingers in the various Soviet murals, the stark architecture and the recurring shape of the Sputnik. Holger unveils the Soviet history of these familiar sites by showing archival photos of the exact spots you visit on his tour, narrating anecdotes and recounting historical facts. The tour leads down Alexanderplatz and Karl Marx Allee, which used to be called Stalin Allee, finally ending at Berlin’s biggest Soviet Memorial in Treptower Park.

Soviet Berlin II lasts four hours and covers five kilometres by foot. It’s perfect for tourists, who would like a unique walk through central Berlin, but as a local I also learned a lot and enjoyed Holger’s extensive knowledge of the subject. Not only was he was able to answer all my questions, but he could recount personal stories about his experience, and those of his friends and family. I would be especially interested in taking his Potsdam and Hinterland Tours, which are more off the beaten track and will certainly take me into as yet unexplored territory.
